Base finite element solution for the calculations of flux and torque of Switched Reluctance Motor, the state equation of SRM is thus educed. In addition, according to the fact that it is difficult to attain the ideal effect with the regulatory linear control method because of the double salient pole SRM structure of stator and rotor, fuzzy control is proposed and used in the sliding mode control to form a intelligent sliding mode control. We emphasize the introduction of the design method of the intelligent sliding mode control and present the control diagram. The simulation results show that the method of intelligent sliding mode Variable Structure Control is simple, with good dynamic performance and robust property.
